BACKGROUND OF THE INVENTION

This invention relates to gardening systems and more particularly to raised bed gardening systems including means to protect the plants from animals.

Raised garden beds are becoming more and more popular both in commercial agriculture and in home agricultural settings inasmuch as they provide numerous advantages over normal-grade garden beds. For example, raised beds permit precise control of soil conditions while offering better water drainage and less soil compaction. The use of raised beds has led to the development of numerous types of containment systems to hold the soil and keep unwanted pests or animals out of the garden. Moreover such systems also include various means for enabling access to the raised bed.

The patent literature includes a number of patents directed to raised bed systems. For example see, U.S. Pat. No. 7,424,787 (Singer); U.S. Pat. No. 7,490,435 (Singer); RE44,055 (Singer); United States Published Applications US2007/0130824 (Teich); US2010/0224848 (Singer et al.); US2011/0252702 (Gazjuk); US 2011/0283611 (Topping); US2013/0174480 (Gabelmann); and European Published Application EP2273040 (Vandermaessen).

While those prior art raised bed systems including enclosures for keeping out animals or pests are generally suitable for their purposes they nevertheless leave something to be desired from the standpoints of simplicity of construction, ease of use and effectiveness. Accordingly, a need exists for a raised bed system which achieves those ends. The subject invention does so.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT

Referring now to the various figures of the drawing wherein like reference characters refer to like parts, there is shown at 20 in FIG. 1 one exemplary embodiment of a raised bed gardening system constructed in accordance with this invention.

The system 20 basically comprises a base 22 and a screened enclosure 24. The base 22 is an assembly of plural planks or beams 26 which are interconnected, as will be described later, to form at least one hollow enclosure that is arranged to be disposed on the ground. In the exemplary embodiment shown in FIG. 1, the system includes two such hollow enclosures 28A and 28B. The interior of each hollow enclosure formed by the planks 26 of the base serve to receive a growing medium, e.g., soil, nutrients, etc. to form a raised bed or garden for growing one or more plants or vegetables therein. The material making up the planks or beams of the base can be any suitable materials which can hold up to typical soil conditions. In accordance with a preferred embodiment of this invention the planks or beams are wood or composite wood.

The screened enclosure 24 is mounted on the base 22 encircling the beds 28A and 28B and includes a series of protective screens that help gardeners keep what they sow in the bed(s), safe from ravaging by large or small animals. To that end the screened enclosure 24 basically comprises a plurality of elongated post or frame members 30, plural upper screen members 32 and plural lower screen members 34. As will be described later the upper screen members are designed to keep large animals, such as deer, out of the garden, while the lower screen members are designed to keep small animals, such as rabbits and ground hogs out of the garden. The post or frame members 30 serve to slidably support the screen members in such a manner than any particular screen member can be individually raised, lowered or entirely removed from the enclosure. This feature provides the gardener with complete and easy access to the contents, e.g., the plants/vegetables, growing in the raised bed(s).

In accordance with one preferred embodiment of this invention the upper screens are located at the top portion of the screened enclosure 24 and are in the form of a relatively large mesh or grid to keep large animals from gaining access to the bed(s) when the screens are in their normal (lowered) position. The lower screens are located at the bottom portion of the screened enclosure 24, e.g., adjacent the base 22, and are in the form of a relatively small mesh or grid to keep small animals from gaining access to the bed(s) when the lower screens are in their normal (lowered) position.

Turning now to FIGS. 2, 7 and 8 the details of the upper screen members 32 will now be described. Each upper screen member comprises a wire mesh or grid panel 36 and a peripheral frame 38. The panel 36 in the exemplary embodiment shown is rectangular, but that shape is merely exemplary. Thus, the panel 36 can be of any shape desired, e.g., square, etc. The resulting upper screen member has a top edge 32A, a bottom edge 32B, and a pair of opposed side edges 32C and 32D. As best seen in FIGS. 7 and 8 the frame 38 is generally U-shaped in cross section so that it can receive the peripheral edge of the mesh panel 36. The mesh panel 36, as noted above, of a relatively large, e.g., 2″ square, mesh or grid and can be formed of any suitable material, e.g., welded steel galvanized wire. The frame 38 can also be formed of any suitable material. In an exemplary preferred embodiment it is formed of aluminum.

The lower screen members 34 are similar in construction to the upper screen members 32. To that end, as best seen in FIG. 3 each lower screen member 34 comprises a wire mesh or grid panel 40 and a peripheral frame 42. The panel 40 in the exemplary embodiment shown is rectangular, but that shape is merely exemplary. Thus, the panel 40 can be of any shape desired, e.g., square, providing that its width is the same as the width of the upper screen member since any particular upper screen member and its associated lower screen member are slidably supported between a pair of adjacent post or frame members 30, as will be described in detail later.

Each lower screen member has a top edge 34A, a bottom edge 34B, and a pair of opposed side edges 34C and 34D. While not shown, the frame 42 is generally U-shaped in cross section, like frame 36, so that it can receive the peripheral edge of the mesh panel 40. The mesh panel 40, as noted above, of a relatively small, e.g., 0.5 inch square, mesh or grid and can be formed of any suitable material, e.g., woven aluminum wire. The frame 42 can also be formed of any suitable material. In an exemplary preferred embodiment it is formed of aluminum.

Even though the lower screen members are of a mesh whose size is smaller than that of the upper screen members, it is nevertheless of sufficient size to allow sufficient sunlight to pass therethrough to encourage plant growth performance in the bed.

As can be seen in FIGS. 1 and 5, and as mentioned above, the post or frame members 30 are spaced from each other and extend upward around the periphery of the base 22. The spacing or gap between adjacent post or frame members is selected to be just slightly larger than the width of the upper and lower screen members 32 and 34, respectively. The post or frame members are of two types, namely, a corner post or frame member 30A and a side post or frame member 30B. Each corner frame member 30A is located at a respective corner of the enclosure 24 to releasably slidably support the respective side edges of the upper and lower screen members at that corner. Each side frame member 30B is located on a respective side of the enclosure 24 between two corner frame members 30A to releasably slidably the respective side edges of the upper and lower screen members on each side of the side frame member.

Turning now to FIG. 7, the details of a typical corner post or frame member 30A will now be described. To that end, as can be seen each corner post or frame member 30A is an elongated member that is formed of any suitable material, e.g., extruded aluminum. Each corner frame member 30A is of square cross section and includes a pair of first elongated, linear channels or track sections 44 projecting outward from respective inside surfaces of the frame member 30A so that the track sections 44 are oriented perpendicularly to each other towards the adjacent bed. The other two surfaces of each corner frame member constitute an outside surface and are directed away from the bed.

As best seen in FIGS. 4 and 6, the track sections 44 are located at the bottom portion of each corner frame member and are arranged to releasably slidably receive respective sides of the frame 42 of the lower screen members 34 at that corner. Thus, the bottom edge 34B of the frames of those lower screen members 34 can be slid to a position immediately adjacent the base 22 like shown in FIG. 1. Each of the corner frame members 30A also includes a pair of second elongated, linear channels or track sections 46 projecting outward from respective surfaces of the frame member 30A so that the track sections 46 are oriented perpendicularly to each other. The track sections 46 are located at the top portion of each corner frame member and are set-back from the position of the track sections 44, i.e., are closer to the bed than the track sections 44. In accordance with one preferred exemplary embodiment of this invention, the track sections 46 are set back approximately 1 inch from the track sections 44. The track sections 46 are arranged to releasably slidably receive respective sides of the frames 38 of the upper screen members 32 at that corner. Thus, the bottom edge 32B of the frames 38 of the upper screen members 32 can be slid to a position immediately adjacent the top edge 34A of the frame of the underlying lower screen member.

Turning now to FIG. 8, the details of a typical side post or frame member 30B will now be described. To that end, as can be seen each side post or frame member 30B is an elongated member that is formed of any suitable material, e.g., extruded aluminum. Each side frame member 30B is of square cross section and includes a pair of first elongated, linear channels or track sections 44 projecting outward from respective opposed surfaces of the frame member 30B so that the track sections 44 are oriented 180 degrees to each other. The track sections 44 are located at the bottom portion of each side frame member and are arranged to releasably slidably receive respective sides of the frame 42 of the lower screen members 34 on either side thereof. Thus, the bottom edge 34B of the frames of those lower screen members 34 can be slid to a position immediately adjacent the base 22 like shown in FIG. 1. Each of the side frame members 30B also includes a pair of second elongated, linear channels or track sections 46 projecting outward from respective surfaces of the frame member 30A so that the track sections 46 are oriented 180 degrees to each other. The track sections 46 are located at the top portion of each side frame member and are set-back from the position of the track sections 44, i.e., the track sections 46 are located closer to the bed than the track sections 44. In accordance with one preferred exemplary embodiment of this invention, the track sections 46 of the side post or frame members 30B are set back approximately 1 inch from the track sections 44. The track sections 46 are arranged to releasably slidably receive respective sides of the frames 38 of the upper screen members 32 on either side thereof. Thus, the bottom edge 32B of the frames 38 of the upper screen members 32 can be slid to a position immediately adjacent the top edge 34A of the frame of the underlying lower screen member, like shown in FIG. 1.

Each of the track sections 44 and 46 is open at the top end thereof. Thus, any lower screen member 34 which is located in the track sections 44 of adjacent frame members 30 can be slid upward, like shown in FIGS. 5 and 6, to any position with respect to its frame members to provide the user with access to the bed within the enclosure 24. In fact, since the top of each track section 44 is open each lower screen member located therein can be slid upward beyond the top end of the track section to completely remove the lower screen member from the enclosure 24. In a similar manner, any upper screen member 32 which is located in the track sections 46 of adjacent frame members 30 can be slid upward to any position with respect to its frame members to provide the user with access to the bed within the enclosure 24. Also, since the top of each track section 46 is open each upper screen member located therein can be slid upward beyond the top end of the track section 46 to completely remove the upper screen member from the enclosure 24.

While not shown, the track sections 46 include a stop at the bottom thereof to prevent the upper screen members from sliding out of the bottom of those track sections. In accordance with a preferred embodiment of this invention each stop is preferably in the form of a pop-rivet located approximately 0.25 inch from the bottom of the associated track section. However, other forms of stops, e.g., a ledge, a wall, etc., can be used in lieu of a pop-rivet.

As should be appreciated by those skilled in the art, by having the tracks 46 holding the upper screen members off-set, e.g., set back, from the tracks 44, the gardener can readily grasp the particular screen member desired to be moved or removed. This enables the gardener to lift or otherwise remove any lower (small animal) screen member 34 to work in the garden through opening provided by the lifted or removed lower screen member, without needing to remove the upper (large animal) screen member located immediately above it.

While not shown, each corner post or frame member 30A includes two pair of projecting walls or flanges. Each pair of walls or flanges is located at the bottom-most portion of the corner post or frame member 30A on the surfaces from which the track sections 44 and 46 project. The walls or flanges of pair are spaced apart by a distance just slightly larger than the thickness of the planks or beams 26, to enable a respective end of a plank or beam to be received therein to form the base. Each side post or frame member 30B includes three pair of projecting walls or flanges which are located at the bottom-most portion thereof. The walls or flanges of two of the pairs project inward from the respective surfaces of the post or frame member 30B from which the track sections 44 and 46 project. In addition, a third of the three pairs of walls or flanges projects inward from the inner surface of the side post or frame member 30B. The walls or flanges of each pair are also spaced apart by a distance just slightly larger than the thickness of the planks or beams 26, to enable a respective end of a plank or beam to be received therein. Thus, the walls or flanges projecting inward from the inner surface of the side post or frame member 30B receive a respective end of a plank or bean to divide the base 22 into the two beds 28A and 28B.

It should be pointed out at this juncture that the height of the walls or flanges of each corner and side post or frame member is sufficient to accommodate two or more planks or beams that are stacked up as shown in FIGS. 1 and 5 to produce a raised bed whose height is a multiple of the height of any of the planks or beams.

While not shown a wire mesh is also preferably disposed under the beds 28A and 28B to protect against the incursion of burrowing animals.

It should be pointed out at this juncture, that various changes can be made to the system of this invention. For example, the post or frame members 30 need not be of square cross section, e.g., they can be of round cross section. Moreover, the corner members need not be arranged so that the upper and lower track sections are perpendicular to each other. Thus, they can be at an obtuse or acute angle to each other, so that the resulting enclosure is not rectangular or square shaped. Moreover, the track sections holding the lower screen members may be set back from the track sections holding the upper screen members. Further still, the system may be configured to provide only a single bed instead of the two beds shown in FIG. 1. In fact the system may be configured to create any number of beds. Further still, the screened enclosure may be constructed so that there is only one upper and one lower screen member, with both screen members being individually slidable to any desired position and also individually removable. In fact, the subject invention contemplates a raised bed system in which the upper and lower screen members are individually removable from the post or frame members, but are not slidably mounted therein. Further still, the subject invention contemplates a raised bed utilizing only a single level of plural screen members, e.g., a plurality of lower screen members, each of which is individually slidably removable from its associated frame sections. Further yet, the size of the screens, and their number is a matter of choice. Thus, for example, the screens may be designed to fit a five foot section of garden so that easy access to the bed to facilitate planting and harvesting can be readily accomplished without the gardener having to step into the bed and compress its soil.

Irrespective of the construction of the system 20, it is also contemplated that other devices and assemblies can be incorporated in it or used with it. For example, while not shown, the system may include a trellis system to permit vertical gardening within the screened enclosure. In addition, the system 20 may include irrigation system, e.g., a battery operated and automatic “drip irrigate” system to irrigate the bed. That irrigation system may include a “rain sensor” to interrupt the automatic irrigation cycle if there is a substantial amount of rain. The system may also include an aviary net arranged to be mounted over the bed to keep out birds, squirrels, etc.

Without further elaboration the foregoing will so fully illustrate our invention that others may, by applying current or future knowledge, adopt the same for use under various conditions of service.
